Vadzo Imaging’s Armor-246CRS-GMSL2 is a 2MP HDR GMSL2 camera designed for automotive and embedded vision systems. Built around the Onsemi AR0246 sensor, this camera brings high dynamic range, long-reach connectivity, and low-power operation to a compact module. For system integrators and OEMs looking for a reliable camera that can handle challenging lighting and installation environments, the Armor-246CRS-GMSL2 offers a compelling combination of features.
The camera leverages on-sensor eHDR technology to capture up to 120 dB dynamic range, which is crucial for scenes with extreme brightness differences, such as a vehicle entering a tunnel or a dashboard camera facing direct sunlight. With Adaptive Local Tone Mapping (ALTM), it preserves details in both shadows and highlights, producing a usable image without requiring heavy host-side processing. The GMSL2 interface ensures stable video transmission over extended cable lengths, making it ideal for installations where the camera is placed away from the host processor.
What is the Armor-246CRS-GMSL2?
The Armor-246CRS-GMSL2 is a 2MP color rolling shutter camera module from Vadzo Imaging’s Armor Series. It integrates the Onsemi AR0246 sensor with a GMSL2 serializer, enabling high-speed data transfer over coaxial cable or shielded twisted pair. The camera supports multiple video formats, including VGA, 720p, and 1080p, and offers advanced features like line-interleaved HDR (LI-HDR) and enhanced dynamic range (eDR) for moderate contrast scenes.
Designed for versatility, the camera is available with various lens and cable options, and can be customized for specific applications. Its compact form factor, measuring just 38mm x 38mm, and light weight of 25 grams (without lens), make it suitable for space-constrained designs. The operating temperature range of -40°C to 85°C ensures reliable performance in harsh environments, from automotive dashboards to outdoor security cameras.
What stands out
High Dynamic Range with ALTM
The on-sensor eHDR achieves up to 120 dB dynamic range, with Adaptive Local Tone Mapping that adjusts the brightness curve region by region. This preserves details in both bright and dark areas, reducing the need for extensive post-processing. The camera’s ability to handle extreme lighting conditions is a key advantage for applications like traffic monitoring and facial recognition.
Long-Distance GMSL2 Interface
The GMSL2 interface supports a nominal forward data rate of up to 6 Gbps, allowing uncompressed 2MP video at 30 fps over long cable runs. This is essential for installations where the camera must be placed far from the host, such as on windshields, poles, or door frames. The robust transmission also handles vibration and electrical noise common in automotive and industrial settings.
Low-Power Wake-on-Motion
Wake-on-motion capability allows the sensor to remain in a low-power state and automatically resume capture when activity is detected. This is particularly useful for dashboard cameras and security systems that monitor quiet areas for extended periods. System designers can measure the wake-up time to ensure it meets their specific requirements.
Compact and Customizable Design
The small form factor and M12 lens mount make the camera easy to integrate into various devices, from wearables to kiosks. Vadzo also offers customization options, including board redesigns, firmware modifications, and integration of additional sensors like ToF or mmWave radar, allowing OEMs to tailor the camera to their exact needs.
